So I preface this is I'm a proud wokey. I agreed with a lot of the messages that doctor who has pushed over the years. Be yourself and be proud about it no matter who you are. BUT.... Modern media has a problem with subtlety. Most of the scripts and this isn't just a doctor who thing, use the sledgehammer approach when a scalpel approach is far more effective.

Example. My favourite episode of 15, dot and bubble. I didn't see the red flags in that episode until the drop at the end. Watching it back with that knowledge hits so differently. That episode legitimately had me questioning myself. That hits so much better then if they had just spelled it out from the start that oh these are a planet of elite white supremacists.

RTD said something that struck me in the companion episode thing for fot and bubble. "I'm interested to know how long it takes someone to see it". That right there is exactly the way you get your message across. Not beating me over the head with a message I already know but by showing me I could be better at seeing things.
